This case study examines this novel moment of democratic experimentation in California, which became known as the Petaluma Fairgrounds Advisory Panel (PFAP). It begins with a description of the context, a summary of the PFAP’s design, composition, and process, and a discussion of the role of the government-lead or sponsor, the Petaluma City Council. An analysis of the impact of participation on the Panelist using a methodology developed by the author in several other case studies follows. Finally, the last section provides several recommendations to enhance the impact of such processes as well as thoughts on the future of deliberative platforms.
